The tube mill is composed by:

- Single Decoiler and Automatic coil car for strip loading

- Coil opener with strip flattener                                     

- Automatic Strip End welder                                                          

- Horizontal Strip Accumulator complete at the exit side of a flying shear for strip cutting

- Strip edge preparation unit           

- The complete LINEAR CAGE Forming group for round tubes (PATENTED BY OLIMPIA80)                                          

- Weld box with HF WELDER 350 kW solid state                                        

- Outside scarfing + chopper roll and Inside scarfing

- Cooling section                                               

- “Traditional” Sizing and straightening unit (for round tubes)

- Universal Driven Turk’s Heads

- Flying Cut-off device by Cold Disk Saw (HSS – TCT)

This Tube mill include some special features as a set of Cassette for Quick roll Change on rails, for welding, sizing and straightening (traditional) units; this system reduce drastically the waiting time when is necessary to change the production size.

The best important news is the Universal Driven Turk’s Heads, positioned after the traditional sizing unit.

The main capacity of the installed machine is from 20x20 (30x10) mm up to 70x70 (100x40) mm, in a thickness range from 0,8 up to 4 mm. With this system the tube mill will produce the full tube range (square and rectangular shapes) without changing any single roll in the sizing turk’s head stands.

The complete group is composed of:

The straightening unit is not motorized and it is placed between the last two heads.

Thanks to the software, the self-centring system allows to place the heads in position 0 (zero) depending on the tube’s size.

The setting for the straightening is made through a control panel placed in front of the head.

This system was engineered to have the possibility to install the complete device even in the existing line alternatively or consequently to a traditional turk’s head.
